I think you guys are missing the point. First, I feel he was just pissed and venting. I'm sure nobody else here has ever said anything in the heat of the moment they regretted later. Secondly, he mentioned the guy in the STI wanted John (9t1GVR4) to follow him down a side road after almost hitting them and after, what I assume may've been some hand signals/words.
Course, I wasn't there so...
